TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 778,910, dated January 3, 1905.

Application filed July '7, 1902- Serial No. 114,624. I

To all whom, it may concern.-

Be it known that LFRIEDRICH SonNNnoKEN, a subject of the King of Prussia, German Emperor, and a resident of Bonn-on-the-Rhine, in the Province of the Rhine, German Ernpire, have invented certain new and useful Improvements in Temporary Binders, of which the following is an exact specification.

My invention relates to improvements'in temporary binders for letters, bills, receipts, and other papers, and more especially to such binders in which two tubular needles are provided upon which the'letters, bills, or the like are filed, whereafter the shanks of the wire bow journaled in the bottom plate are turned so that the points of these shanks are situated in the upper openings of the tubular needles, and each shank of the wire bow forms, together with the respective tubular needle, a closed bow. In these devices the opening and closing of these latter bows, which is effected by turning the wire bow journaled in the bottom plate, is usually eifected by means of a lever to which a nose or pin is fixed, by the down movement of which nose or pin the wire bow ismoved. Now it is a great disadvantage that the nose or pin of the lever in closing the device had to overcome great frictions, in consequence whereof the working of the device sometimes was very difiicult. By the present invention this disadvantage is done away with by arranging the pivot of this lever not in a fixed point, but so that the same can move in a slot.

My invention is represented in the accompanying drawings, in which* Figure 1 is a front view of the binder in the closed position. Fig. 2 is a front view of the same in the open position. Fig. 3 is a section'on lineA B of Fig. 1. Fig. 4 is a plan of the binder.

The lever (0, provided with a pin 6 and adapted to oscillate the wire bow cl, is journaled bymeans of a pin g in a slot 0. Underneath that part of the wire bow (Z which is situated underneath the pin Z) a spring 6 is situated, which effects the opening of the device. In the slot 0 a small cut-out f is situated, in which cut-out the pin g of the lever ct is situated when the device is closed. It is hereby attained that in moving the lever a up and down the pin g slides in the slot 0, so that the pin 6 is moved vertically upward and downward and no friction can arise between the wire bow (Z and this pin g.

Having thus fully described the nature of my said invention, what I desire to secure by Letters Patent of the United States is In a temporary binder for papers, the combination with two tubular needles, and a turnable wire bow consisting of two U-formed shanks capable of forming a closed loop when turned so as to touch the point of the tubular needles, and of a U-formed middle piece connecting these two shanks, of a plate situated perpendicularly to the bottom plate of the device, said plate being provided with a slot, a lever pivoted in this slot and provided with a pin guided in this slot and resting upon the U-formed middle part of the turnable wire bow, and a cut-out portion provided in the vertical plate, said cut-out portion forming an enlargement of the slot and being situated at the spot at which the pivot of the lever is situated in the closed position of the device, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRIEDRICH SOENNECKEN.
